– basically, why is the structure the way it Is. Moreover, what significance can we attribute to this matter of fact? Thanks!
In: Earth Science
Because of gravity. Gravity pulls everything towards the center of the earth. A ball is the most compact shape. Though that’s not quite true. Earth also spins, and things that spin tend to get more of a pizza shape (that’s why you can make pizzas by spinning the dough). Since earth is very heavy but doesn’t spin fast, it’s still mostly a ball, but not quite.
